"The fans they can do what they want". United's first team have been held to struggle against the top teams, but have beaten Spurs, Arsenal, Chelsea and Liverpool in the league this season.
Martial exercised normally with his teammates after having missed Manchester United's last two wins against Liverpool and Crystal Palace.
"He's fantastic. He was one of the best players on the pitch, so I am happy that we have him in the team, and he needs to continue in this way". They've also spent this season looking up at Manchester City, now 13 points ahead of United at the top of the table. "United first half and Liverpool second, but in my opinion our first half was a half with goals and danger", he said.
"When he chose to break the intensity of the game... that was a wonderful solution that some more experienced players wouldn't make and the fans reacted against the kid".
But as far as the season is concerned, there is still a lot of work left for Mourinho to do, if he is to take United to "where they belong", something which he emphatically promised when he replaced Louis Van Gaal at helm.
"In these types of games, when the pressure is on you, you just be yourself and I think that's what seems to happen in these games and the team seems to react well, when maybe we don't react as well in other games".More news: Netanyahu warns Israel could face snap elections

Jose Mourinho has made Old Trafford into a fortress and is the master of grinding out results when he really needs to. Christian Nkuknku, who didn't see a minute in the two Champions League fixtures against Real Madrid, scored twice while there was goal each for Thomas Meunier, Kylian Mbappe and Thiago Silva as PSG continued their unchallenged march to the league title. "Now I have only one name and that is Sevilla, I know is very hard to go through".
And Mourinho remains unsure over Pogba's recovery in time for Tuesday.
West Bromwich Albion's woes continued as they slipped to a 4-1 home defeat by Leicester City.
"If we manage to win the tie and go to last eight, I think [it] is a good achievement but life goes on and hypothetically, we have a quarterfinal to play and we don't go thinking we don't have a chance".
"They didn't use some chances also but, in the end, the most important thing is three points". "It is a joy to play next to him".
"His determination to improve is the biggest feature I've picked up from his game", Rashford said of his team-mate.
